IMPROVD WOODEN PAVEMENT.

The Schedule referred to in these Letten Patent and making part of the same. i

To all 'whom it may concern:

Be it known that I, LAWRENCE HoLMs, of Paterson, in the county of Passaic, in the State'of New Jersey, have invented certain new and useful Improvements in Wooden Pavements; and I hereby declare that the following is a tull and exact description thereof, reference being had to the annexed drawings, making part of this specification, and to the letters and tiguresof inference marked thereon, in which.

Figure I is an end view of a longitudinal section of the paving-blocks. v g

Figure Il, a side view of a transverse section.

Figure Ill, a perspective view. f

My invention consists, tirst, in constructing the supcrstrm-ture of a pavement of wooden blocks, having overlapping portions at their ends and sides, and so cut and adapted to cach other-as to form longitudinal or transverse channels, or hoth, to be 'tilled with Concrete or cement, said grooves serving to give a foothohl to animals travelling on the pavement.

It also consists in the. construction of a wooden pavement ot' blocks, having overlapping portions at theends and sides, with channels, either longitudinal or trans-` verse, or both, between them, which are filled with concrete orvcemcnt, said blocks resting on a layer of semi-elastic cement, laid overa concrete substratum, or tbundation, as hereinafter specified.

.The wooden blocks, seen in the several figures, are

cnt from planks of propel thickness, and the grainof the wood set in a position perpendicular to the pressure to be sustained.

A, in the several figures, represents the end of the wooden paving-blocks; a, the lap, and b, the shoulder upon which the lap rests, and whichalso sustains the concrete filling C of the grooves or channels.

A', Figs I and III, shows a block, in cross-section,

` with the lap (t and shoulder b plainly seen.

B, Figs; lI-and III, shows the sideof the blocks,

with the laps a', shoulders b', and `channels c', the object of the channels cbeing to prevent the lateral slip ofthe feet of horses, or other animals, travellingupod the pavement.

C indicates a concretsubstratum, or foundation, composed of broken stone or gravel, with hydraulic or other suitable cement.

I), an asphalt-ie or bituminous lining, interposed between the concrete foundation and the wooden pavingblocks, and upon which the b locks rest and are secured, in the manner heretofore described.

l do not limit myseh to the combination otthe before-described wooden blocks, for paving-purposes, with a grouted or concrete foundation, with or without an asphaltic or bituminous coveringgas my block may be used with other foundations, such as wooden plank, or, in certain favorable localities, without other substratum than the natural bed.

I do not claim, broadly, a wooden pavement, between the blocks of which are channels or grooves, filled witli concrete or cement, for such has been used before.

What I claim, in blocks for wooden pavements, is

1. Wooden paving-blocks, formed with overlapping portions a af, and shoulders b b', when so cut and adapted to eachother as to form eitherlongitudinal or transverse channels c c', or both, to be tilled with concrete or cement, substantially as herein described.

2.l A pavement constructed of wooden blocks, having overlapping portions at the ends and sides, with channels, either longitudinal or transverse, or both, between them, whioh are iilled with cement, said blocks resting-on a l: yer of semi-elastic cement, laid overa concrete snbstratuln or foundation, substantially as herein described.
